Rumble 500 : Surprisingly loud!

This amp is brilliant, capable of full tonal communication and handles bass effects very well. Although is oversold as a 500w amp it's important to note that it's about 375w without a 8ohm extension cab, but by no means is this an under powered amp. It is plenty loud for your average band situation (unless your rhythm guitarist is playing down-tuned through a bass head). This amp also more than holds it's own in medium sized venues and consistently delivers a solid tone (it is important to remember though that you need a good bass to get a good amp tone). The effects section of the pre amp is quite impressive, VINTAGE turning any bass into a pretty good emanation of a 60s p-bass tone, CONTOUR bringing a decent slap tone and BRIGHT being pretty much useless if your bass has good pickups.
